Limiter waveguides in which a hybrid EH/sub 11/ wave is excited are used as the deflectors for the rf separator. The deflector is designed to optimize the intensity of separated particles, with the subsequent recovery taken into account. The deflectors are fabricated from oxygen-free copper, machined with diamond tools, and silver-soldered in vacuum. The vacuum system for the deflectors provides a limiting vacuum of 10/sup -7/ torr. For improved operating reliability of the deflectors at high power levels, a protection system is provided to suppress the excitation of the high-power output klystron for an interval of 0.15 ..mu..sec after breakdown occurs in a section. The basic characteristics of the hybrid-wave propagation in the deflector (the phase advance in each cell, the damping, and the internal reflection) are measured by a nonresonant-excitation method. The deflector imparts a maximum transverse momentum of 25.1 MeV/c to the particles to be separated at a power level of 20 MW and at a working frequency of 2797.5 MHz. This momentum differs from the calculated value by less than 6%. (AIP)
